Is It Normal for Children to Hold Their Breath?

My 2-year-old recently started to hold his breath when he doesn't get what he wants, and it terrifies me. Is this normal?– LaVonne

As frightening as it might be when your son holds his breath, it's actually quite common among toddlers — and is likely to be more alarming to you than it is dangerous for him.

The best response to such behavior is to make sure he is safe, keep him lying down on his side, and try to stay relaxed. Most kids outgrow breath-holding episodes by the time they're 5 or 6 years old.

Occasionally, kids may pass out for 30–60 seconds during a breath-holding spell. If this happens, talk with your doctor to be sure nothing more serious is going on. The doctor might want to test for anemia, which is sometimes associated with breath holding. When the anemia is treated, kids are often less likely to pass out when holding their breath.
